[phenixbb] calculating a phased anomalous difference map for twinned data in phenix.refine

Hi,

to confirm the nature of a metal ion in my active site, I want to 
calculate a phased anomalous difference map in phenix.refine. However my 
crystals in SG P3(2) are twinned with twin law h,-h-k,-l and a fraction 
of about 40%. Is there a way to calculate an informative map in 
phenix.refine in this case?

best
Michael
